Hi @Vincent_Terrasi , thanks for submitting this issue! I was able to reproduce what you were talking about. It looks like what is happening is that streamlit is trying to use localhost 8501 and same with when the language_tool_python is trying to download. As a result, there is a problem.
Maybe you can try running looking at this forum issue and running streamlit with a different port!
The main answer that is relevant to you I will post here:
There is a param called server.port. So you can do something like: streamlit run streamlit_app.py --server.port 8080
Here is the link if you want to learn more: How to set a different port number for different streamlit program in a same machine?
